Building a code for SSI encoder on FPGA

[aakar_89]

Hello, 

I am fairly new to LabView and I am trying to get an Absolute encoder working using a NI hardware and LabView. 

The encoder that I am usign is http://www.rls.si/rm22-rotary-magnetic-modular-encoder. I am using the cRIO 9114 as the master and NI 9505 for reading the absolute encoder. When I searched the NI Community for a similar issue, I found this link https://decibel.ni.com/content/docs/DOC-1095.  

I took a look at the code that is given in this folder but it sems to have a lot of borken wires or incorrectly attached wires. I am looking for a solution to either fix that or if someone has experience with developing the block diagram for a similar applicaition. 

Thanks 

Aakar

Hi Aakar,

The NI 9505 module is used to drive a servo motor. Unfortunately, this means it will not work to read an encoder. To read an encoder, you would need a digital input module. For SSI, you actually would need a differential digital module, such as the NI 9411. 

As for the code, have you installed the FPGA and Real-Time Modules? After unzipping the code and opening the LabVIEW Project file, everything appeared ok. 

I hope this information helps you in creating your application.

Have a nice day,

Andrew
